How often do we replace?.

As I recall, replacement is every 3 months or 1500 gallons of water used. At that point the unit beeps each time you turn the unit on. I live alone and don't use that amount, so I just live with the beeping to stretch out the time before replacing.

I've been changing mine every two months. Honestly not sure how often they are supposed to be changed.

It all depends on how much you use them, but for me i use them everyday with high dust content so I replace them every few months

We change ours once a year. Not sure if that is what is recommended though...

Depends on use. I replace mine every 6 months. But I also keep my hot tub very clean and wash filter every month.

I use them every day. I walk a lot and replace every 6 to 8 weeks. I think you'll like them

depends on your water source and how much you use the maker. We change ours every 3 months

Yes! I don't know their longevity? If it comes time to replace one , I'm sure you will see "tell-tale " signs that it's appearance has changed enough to warrant replacement. I don't use them on a daily basis, just 2-3 times a week. I personally feel they are excellent. Compare them to others, watch " U-Tube", you will get the idea quickly.

I change mine about every 6 months, but I only use it at work. It doesn't get everyday or all day use.

I replaced mine when it was not working anymore. Otherwise if it's cleaned well, you don't need to replace it often or at all.

It depends on the usage. I use my when I travel, which is about a dozen times a year for about a week each time and they have lasted for years.

It depends on usage. The Everpure website states that they should be replaced once a year. But it also states that they have a 1000 gallon capacity. I take this as meaning replace once per year or every 1000 gallons whichever occurs first.Another indicator that you need to replace the cartridges is when the water flow out of them has diminished significantly.

Sonicare says replace every 6 months maximum. Depending how often you brush, the force you use against your teeth, and the number of people using the brush (for those who like to share), it varies. I've been replacing mine every six months or so. A two pack lasts a year and is generally cheaper to buy than a single brush head. Don't be afraid to rinse the brush head under water to clean it. Let it dry before you use again. Never immerse the handle/body in water, however.

I replace it weekly. It depends on your beard. Mine is on the light side of average.

I've replaced the blades sometime after the razor stopped reminding me to - on average that's about every 15 months. As others have written I have not yet replaced the foil although it is recommended to do so after a couple of blade swaps. I figure that the razor will need replacing sooner as the battery life has dropped over the 4 years that I have had it and the foil cost is a significant way towards a new shaver!

I replace mine once a year. A lot depends on how clean your house is and if you have pets that shed hair. I have two cats.
